Due to the scientific and cultural importance of the Chiquibul National Park, and the sinkholes within, it will likely become a UNESCO World Heritage Site. There's a plan to study the area for around a year. More pictures from the expedition.
"An historic expedition of a 425’ sinkhole located in the Chiquibul National Park of Belize may prove to reveal rare and possibly never-before-seen plants from the heart of the ancient Mayan civilization. The area’s scientific, historic, and cultural significance makes it a likely candidate for a UNESCO World Heritage site designation."
